DESCRIPTION

29       "TAP::Parser::Aggregator" collects parser objects and allows
30       reporting/querying their aggregate results.
31

METHODS

33   Class Methods
34       "new"
35
36        my $aggregate = TAP::Parser::Aggregator->new;
37
38       Returns a new "TAP::Parser::Aggregator" object.
39
40   Instance Methods
41       "add"
42
43         $aggregate->add( $description => $parser );
44
45       The $description is usually a test file name (but only by convention.)
46       It is used as a unique identifier (see e.g.  "parsers".)  Reusing a
47       description is a fatal error.
48
49       The $parser is a TAP::Parser object.
50
51       "parsers"
52
53         my $count   = $aggregate->parsers;
54         my @parsers = $aggregate->parsers;
55         my @parsers = $aggregate->parsers(@descriptions);
56
57       In scalar context without arguments, this method returns the number of
58       parsers aggregated.  In list context without arguments, returns the
59       parsers in the order they were added.
60
61       If @descriptions is given, these correspond to the keys used in each
62       call to the add() method.  Returns an array of the requested parsers
63       (in the requested order) in list context or an array reference in
64       scalar context.
65
66       Requesting an unknown identifier is a fatal error.
67
68       "descriptions"
69
70       Get an array of descriptions in the order in which they were added to
71       the aggregator.
72
73       "start"
74
75       Call "start" immediately before adding any results to the aggregator.
76       Among other times it records the start time for the test run.
77
78       "stop"
79
80       Call "stop" immediately after adding all test results to the
81       aggregator.
82
83       "elapsed"
84
85       Elapsed returns a Benchmark object that represents the running time of
86       the aggregated tests. In order for "elapsed" to be valid you must call
87       "start" before running the tests and "stop" immediately afterwards.
88
89       "elapsed_timestr"
90
91       Returns a formatted string representing the runtime returned by
92       "elapsed()".  This lets the caller not worry about Benchmark.
93
94       "all_passed"
95
96       Return true if all the tests passed and no parse errors were detected.
97
98       "get_status"
99
100       Get a single word describing the status of the aggregated tests.
101       Depending on the outcome of the tests returns 'PASS', 'FAIL' or
102       'NOTESTS'. This token is understood by CPAN::Reporter.
103
104   Summary methods
105       Each of the following methods will return the total number of
106       corresponding tests if called in scalar context.  If called in list
107       context, returns the descriptions of the parsers which contain the
108       corresponding tests (see "add" for an explanation of description.
109
110       ·   failed
111
112       ·   parse_errors
113
114       ·   passed
115
116       ·   planned
117
118       ·   skipped
119
120       ·   todo
121
122       ·   todo_passed
123
124       ·   wait
125
126       ·   exit
127
128       For example, to find out how many tests unexpectedly succeeded (TODO
129       tests which passed when they shouldn't):
130
131        my $count        = $aggregate->todo_passed;
132        my @descriptions = $aggregate->todo_passed;
133
134       Note that "wait" and "exit" are the totals of the wait and exit
135       statuses of each of the tests. These values are totalled only to
136       provide a true value if any of them are non-zero.
137
138       "total"
139
140         my $tests_run = $aggregate->total;
141
142       Returns the total number of tests run.
143
144       "has_problems"
145
146         if ( $parser->has_problems ) {
147             ...
148         }
149
150       Identical to "has_errors", but also returns true if any TODO tests
151       unexpectedly succeeded.  This is more akin to "warnings".
152
153       "has_errors"
154
155         if ( $parser->has_errors ) {
156             ...
157         }
158
159       Returns true if any of the parsers failed.  This includes:
160
161       ·   Failed tests
162
163       ·   Parse errors
164
165       ·   Bad exit or wait status
166
167       "todo_failed"
168
169         # deprecated in favor of 'todo_passed'.  This method was horribly misnamed.
170
171       This was a badly misnamed method.  It indicates which TODO tests
172       unexpectedly succeeded.  Will now issue a warning and call
173       "todo_passed".
